The Dirac bracket is a concept used in the context of constrained Hamiltonian systems in classical mechanics, developed by physicist Paul Dirac. It allows for the consistent formulation of dynamics in the presence of constraints, particularly when dealing with first-class and second-class constraints. Here’s a brief overview of what the Dirac bracket is and how it is used: \#\#\# Background Concepts 1.
